This time please follow me to know the specifications of the metal dome.
1. The material: our stainless steel of metal domes are made from type 301 SUS. This material we choiced as it’s with low carbon persent (10%) which offers the best oxidiation resistance. We purchase the material from USA and Japan.
2. The thickness: Normally, the thickness is 0.06mm, 0.08mm, 1.0mm, 1.2mm.
3. Click ratio: CC: Click Ratio; CP: Compression Peak Force; CL: Compression Low Force; RL: Release Low Force; RP: Compression Peak Force
CC(%)=(CP-CL)/CP x 100%, it’s normally between 35% and 60%.
4. Height: The height is equal the stoke + thickness of the metal dome.
5. Life Expectancy: Life cycles of our metal domes are from 300,000 to 1000,000 times. The life expectancy of our metal domes is very stable.
6. Plating: There are three types for plating: Nickel plating, silver plating and gold plating are available.
